Well technically I may use both of the options. I mean, I have a backup .ui file but I'm quite unsure about to use it because I'm not sure I'll remember all the changes - and they were quite a few. And also that may take quite a considerable time.
About the second option, I'm glad it can be solved so, but in that case what should I do? attach the .ui doesn't sees to be possible here in the forum. Besides, could it be too much difficult to find the error or this can be done quickly? Because I don't want to waste your time :T
